Interior Space and Exhibition Design RMIT Bldg 88 Upholstered Joinery by Peter Rattle for CUS (Vic) Pty Ltd The Buildings design concept was to provide a unique but standardised work enviroment. By limiting the amount of built-in joinery to specialised Banquette Seating and componentry, communal benches and loose furniture, the space has not only been designed for its current occupants, but also considers the inplications of future expansion.
